To all whom t may concern BeA it known that'l, JAMES J. Woon, a citizen ofthe United States, residing at Fort Wayne, county of Allen, State of Iiidiaiia, have invented certain new and useful Improvements in LiquidfMixers, of which the following is a specification. l

My invention relates l,to .that type of'apparatus which is adapt d to violently agitate the contents of a' l/iequid containing receptacle, and is more particularly designed for mixing drinks.

The objects of my invention are generally to improve and simplify the present construction of such apparatus, and more specifically to provide means for readily and easily moving all parts of the'apparatus simultaneously from an ino erative to an operative position, and similarly back to the inoperative position.-

A further object of my invention is to provide positive means for holding the several arts of ,the apparatus in van operative position, so that the agitation may proceed without the attention of an attendant, and further to provide means for holding the liquid receptacle at several heights so that the time required for mixing the liquid may lbe varied/'to suit the convenience of the attendant. I

The invention comprises a relatively fixed motor-driven agitator or mixer coperating with a' support for a liquid containing re ceptacle, they latter adaptedto move into andy out, of operative relation with the agitator. The motor is similarly and simultaneously controlled by my improved and simplified construction, so thatl while the liquid receptacle is in a raised or operative position, the agitator, is rapidly rotating,

and,I conversely, when the receptacle is lowered, the agitator is at rest. By my irpproved construction, the motor-driven agitator is relatively fixed, and the receptacle holding the liquid to be mixed is moved into operative relation with the agitator, thus materially diminishing the wea-r and tear on the rapidly moving parts.

Re'ferringto the drawings, Figure 1 is a side elevation partly in section and showing my improved forni of motor controlling mechanism. Fig. 2 is a front elevation, certain parts being broken away and shown in section and/other parts entirely omitted, for the sake of clearness.

v`them.

insulating material to which is secured by screws, or other suitable faste-ning means, a short hollow standard 4. In the top of this standard there is fitted al hollow vertical .supporting member 5, provided at its top with a hollow arm 6, to which is vsecured a small electric motor 7. The armature shaft has secured to and depending from it a rod 8 carryin an agitator or mixing member 9.

The ho low standard 4 is provided with lugs 10 and `11 which form bearings for short horizontal shafts 12 and 13. Arms 14 and 15, each having bifurcated or yoke ends, -are secured at one end to the shafts l2 and rod 18 depending from a flatcircular suport 19. The arm 15 has an integral pro- ]ection 16 extending beyond the rod 18 and adapted to act as a pawl in coperation with a pivoted ratchet member 17, the pivot'of A. guard the liquid is not mixed so Well in a given position. 4

A rigid strip of insulating material 22 lis fastened near the bottom of the standard 4, and secured to this strip are twofsimilarbinding posts 23. Spring contacts 24, lia`viiig Hat contact surfaces, are mechanically posts. The spring contacts are adapted to be separated by an arm 26 keyed to the shaft'13, and provided with-a round piece of the `two spring contacts apart. The upper ends of the spring. contacts are made flaring for the easy entrance of the arm 26 between The current supply Wires 27 enter the hol- 13 res ectively, and the other" bifurcated ends o `these arms are pivoted to a vertical such ratchet member being the same as the l and electrically connected to the binding insulation through the end where it presses c The apparatus .is supported by .a base 3 of i of this motor is in a vertical position and venience,for if the glass is in mid position,

'time, as it would be ifheld 'in the top-most 'low' standard near t-he bottom thereof` through a-bushing 278. One of these Wires 29 passes t-hrough the hollow members 5 and 6 and is connected to one terminal of the motor. The other current supply Wire 30 is connected to one of the binding posts 23. A third Wire 31 passes from the second in Fig. 1, the rod 18 is resting upon the base 3 and the glass 21 is in its lowest position, this position being such thaty the glass can be readily moved from its support without spilling its contents. The insulating arm 26 is in 'engagement with the contacts 24 and the electric circuit to the mot-or is therefore broken. When it is desired to agitato the contents of the glass 21, the operator grasps the thumb piece of the ratchet member 17 and the support 19 and raises the glass 21. The arm 26 is simultaneously raised and no longer ,acts to hold the contacts 24 apart.

The elect-ric circuit 'through the motor is.

therefore complet-ed and the rod 8 and agitator 9 are rapidly rotated, thereby thoroughly mixing the contents of the glass. When the glass is in a raised position, the paWl 16 is adapted to engage one of the notches of the ratchet 17 and -Will thus hold the apparatus in an operative position, as shown in dotted lines in Fig. `1. When the mixing is completed, the ratchet is released from engagement with `its pawl and the apparatus restored to its original or inoperative position.

What l claim as new and desire to secure by Letters Patent of the United States, is

1. A liquid mixer comprising an agitator, a movable member adapted to support a liquid containing receptacle and to be moved into and out 0f operative relation 'With said agitator, and means operated by the movement of said member for controlling the operation of the agitator.

2. A liquid mixer comprising an agitator, a. movable member forming a supportfor a liquid containing receptacle and adapted to bc moved into and out of operative relation with said agitator, means operated by the movement of said member for controlling the operation of the agitator, and positive means for locking said parts in operative position. i

3. Ay liquidmixer comprising an agitator, a movable member forming a support for a liquid containing receptacle and adapted to be moved into and out of operative relation with said agitator, and positive means for locking said liquid receptacle in one of several operative positions.

4. A liquid mixer comprising a relatively fixed agitator, a motor for rotating the agitator, a movable,support for holding the.H

liquid containing receptacle said support and receptacle adapted to be moved into operative relation with said agitator, means operated by the movement of the support and the receptacle for controlling the motor and placing it in operation, and positive means for holding said parts inoperative relation.

5. A drink mixer comprising a support, an electric motor rigidly secured thereto, an agitator fixed to and depending from the shaft of said motor, a movable member comprising a support for a liquid containing rece atacle and an insulating arm, spring contacts adapted to be separated by said arm when the mixerf is in an inoperative position and to close the electric circuit through the motor When the mixer is in an 'operative position, and means for positively holding the parts in an operative position.

In Witness whereof, l have hereunto set my hand this 30th day of January, 1912.
